prolongation
Making something longer
Prolongation is the act of extending something in time or duration: The prolongation of the negotiations frustrated both sides.
It can also refer to the extended portion itself—an addition that lengthens what already exists.
The word appears in formal or technical contexts more often than everyday speech, where "extension" typically serves the same purpose.
